Please be aware that there are 3 costs involved in a foundry (I wish I
could remember or find where I read this).
1. The cost of building it. Really big.
2. The cost of starting it up for the first time. AFAIR 1/2 of the cost
   of building it.
3. The cost of running it. Normally the customers pay for this.

So, just having the funds to build a foun doesn't mean we can start
producing chips.
